As a result of the new software update, loaded today, I am unable to launch the UI of Avast. When I click on Restart Service, a new screen pops up and is immediately replaced by the Restart Service screen. I have rebooted 5 times with the same result.Using a Surface Book with Windows 10 Pro, version 1803., 64-bit.Have another Win 10 desktop computer 64-bit which was able to successfully run Avast after install. Received the same error as above, but after rebooting 3 times it started correctly.

After a couple more reboots, Avast came up successfully. Only additional action I performed prior to final reboot was to enable Windows Defender firewall for Domain, Private, and Public. Probably had no impact on the Avast result, but just wanted to pass that on.
